Hi:

When I execute the PNOISE and PSS analysis in determining the phase noise of the QVCO designed, the plot is not displayed, whereas an error indication says:

"Output nodes of pnoise analysis not saved for pss analysis. As a result, the above selected function cannot be executed."

I had done the same procedure in determining the phase noise of a LC-tuned VCO, where there is no problem in executing the phase noise plot. But when I configure the QVCO from the VCO topology the phase noise execution fails. Pls do guide me in obtaining the Phase Noise Plot. Thanks in advance
